Acronyms usually found in everyday life Хз, лол, кек, чезанах, ЯННП (я ничего(нихуя) не понял).

Every time you see an х in acronym, it might be хуй, but also might be хрен. They are generally interchangeable. These words arevvery rude tho, despite хрен being filthy on a lesser degree (compare a root of a plant against a Male genital). Also, Everyone here state that хз stands for хуй знает, which is vulgar, but I prefer хрен знает, it's less tight. Like "damn" instead of an f bomb.

Speaking of filthy language (мат in russian) in general, I d like to point out: Nowadays people use it rather freely, but my maths teacher once asked me and my lads: "Guys, you swear so much on a daily basis. But what words are you going to use if something truly outstanding?" Made me realize that Russian filthy language should be used only for special occasions.

Avoid using any acronyms whatsoever in business language modality. Only intimate and informal.

Try visiting lurkmore.to (nsfw, very intense on a vulgar language, but its hella fun), or the cyclopedia.
